Titans Grave: The Salvage of Cortana

Massive Damage Threshold

Massive Damage Threshold

Massive Damage Threshold = Full Health/2 (round down).

If a Player Character (or Non-Player Character, including most monsters) takes half or more of their Health from a single attack, after adjusting for armor soak, they will need to perform an Average Constitution check. (DC 11)
A successful check means the target took the damage and is no worse for the wear.
A failed check puts the character in a Dying status and reduces the character to 0 Health.
The character becomes unconscious and is dying, but can still become stable or be helped by his friends, just like any other character who is reduced to 0 Health.
Again, there is no system of Negative Health in FAGE. Characters will have 2 + Constitution rounds before they expire.
Minion class NPCs and Monster will be considered dead at 0 Health.
